Global warming, melting ice
After giant snow and ice storms blanketed Mississippi, it may not be a good time to talk about global warming.
If you don't believe in global warming, how do you account for the 2 trillions of ice that has melted since 2003? Alaska, Antarctica, and Greenland have seen giant shrinkages in their landlocked ice caps, and Greenland's ice loss would fill 11 Chesapeake Bays.
The ice loss is confirmed by NASA satellite data.
Landlocked ice doesn't raise sea levels, but data from the Arctic north of Alaska shows an ominous trend of warming that is increasing the melting of sea ice. As sea ice melts, the water absorbs more of the sun's energy and warms to higher temperatures while holding those temperatures. This, in turn, melts more ice. As the ice melts, it no longer offers reflective protection against the sun's energy. Parts of the arctic were 9 to 10 degrees warmer last year, than in previous years.
One scientist noted, “The pace of change is starting to outstrip our ability to keep up.”
On a different note: my new free e-book is available! From the Front Porches of Charleston:" The Election of Barack Obama, a free e-book with 100 photo pages from Barack's photostream features posters, rallies, and intimate looks at Barack and his family.
